A retrospective cohort study. ⋯ This study found that RE occurred at a similar rate in patients treated with ADR and ALIF with BMP. The overall rate of RE after retroperitoneal anterior lumbar surgery was higher than expected, which underscores the importance of counseling patients about this risk and specifically questioning patients about the symptoms of RE at postoperative visits.

Retrospective cost-effectiveness analysis. ⋯ This cost-effectiveness analysis reports favorable results for ACDF procedures utilizing a tantalum implant. The data reported suggest that using porous tantalum as a stand-alone device is less costly and more effective than autograft and plate in ACDF procedures.

An in vitro biomechanical study on 3-dimensional flexibility of human lumbosacral motion segments after multiple freeze-thaw cycles and cumulative testing. ⋯ The flexibility of the human cadaveric lumbosacral motion segments between test days was significantly affected after repeated freeze-thaw and cumulative testing cycles. Multiple freeze-thaw cycles and cumulative testing, however, does not affect flexibility data for tests carried out within a single test day.

A prospective interventional trial, using a rat model of lumbar interbody fusion. ⋯ Our study suggests that using PRP with HA was beneficial for spine fusion. This combination may promote bone union and also decrease inflammatory neuropeptide in sensory neurons innervating the discs.
